Sanitize nipple prior to first use by placing in an open pan of boiling water for 2 minutes. Clean all parts with hot water and mild detergent, or use top rack of dishwasher. Heating Instructions: Place under hot running water or place in a container of heated water, or microwave bottle only (remove nipple, collar, and hood) at 10 second intervals. DO NOT OVERHEAT. Always check temperature on wrist before feeding baby.

All rubber nipples can wear out. To prevent a possible choking hazard, test strength by pulling on bulb portion before each use. Inspect and replace if nipples become sticky, enlarged, cracked or show other signs of excessive wear. Do not allow baby to take a bottle to bed or self-feed for long periods. Extended contact with milk, formula, juice or other sweetened liquids may cause severe tooth decay.
